On the average lower 2-domination number of a graph
(Işık University Press, 2019)Computer scientists and network scientists want a speedy, reliable, and nonstop communication. In a communication network, the vulnerability measures the resistance of the network to disruption of operation after the failure ... -
SK indices, forgotten topological indices and Hyper Zagreb index of Q operator of carbon nanocone
(Işık University Press, 2019)Carbon nanocones are conical structures made from carbon and they have one dimension of order one micrometer. The physical features of these structures can be easily understood by exploiting topological indices. In this ... -
On star chromatic number of prism graph families
(Işık University Press, 2019)In this paper, we find the star chromatic number ?s for the central graph of prism graph C(Yn), line graph of prism graph L(Yn), middle graph of prism graph M(Yn) and the total graph of prism graph T(Yn) for all n ? 3. -
Existence of nonoscillatory solutions of second-order neutral differential equations
(Işık University Press, 2019)We obtain some sufficient conditions for the existence of nonoscillatory solutions of nonlinear second order neutral differential equation with forcing term. Our results improve and extend some existing results. Examples ... -
Global color class domination partition of a graph
(Işık University Press, 2019)Color class domination partition was suggested by E. Sampathkumar and it was studied in [1]. A proper color partition of a finite, simple graph G is called a color class domination partition (or cd-partition) if every color ... -
Existence of three solutions for impulsive fractional differential systems through variational methods
(Işık University Press, 2019)This paper is devoted to the study of the multiplicity results of existence of solutions for a class of impulsive fractional differential systems. Indeed, we will use variational methods for smooth functionals, defined on ... -
Analytic approach for love wave dispersion in an inhomogeneous layer lying over an irregular porous half-space
(Işık University Press, 2019)The present work examines the possibility of Love wave dispersion in an irregular interface of two different media expressively as an inhomogeneous layer and porous half-space. Dispersion equation has been computed in a ... -
Nonexistence of positive solutions for a systems of coupled fractional bvps with p-Laplacian
(Işık University Press, 2019)We investigate the nonexistence of positive solutions for a system of nonlinear Riemann-Liouville fractional differential equations with p-Laplacian two-point boundary value problem. -
Generalized power Pompeıu type inequalities for local fractional integrals with applications to Ostrowski's inequality
(Işık University Press, 2019)We establish some generalizations of power Pompeiu’s inequality for local fractional integral. Afterwards, these results gave some new generalized Ostrowski type inequalities. Finally, some applications of these inequalities ... -
Distance spectra of some graph operations and some new distance equienergetic graphs of diameter 3
(Işık University Press, 2019)Two graphs of same order are said to be distance equienergetic if their distance energies are same. In this paper, we first give a partial insight on the distance spectrum of Mycielskian graphs and then we focus on ... -
Some new results on integer additive set-valued signed graphs
(Işık University Press, 2019)Let X denotes a set of non-negative integers and P(X) be its power set. An integer additive set-labeling (IASL) of a graph G is an injective set-valued function f : V (G) ? P(X) ? {?} such that the induced function f+ : ... -
Existence of nonoscillatory solutions for second-order nonlinear neutral differential equations with variable delays
(Işık University Press, 2019)In this work, an attempt is made to discuss the existence of nonoscillatory solutions of second order nonlinear neutral differential equations with variable delays. The main tools are Lebesgue’s dominated convergence theorem ... -
On the spectra of cycles and paths
(Işık University Press, 2019)Energy of a graph was defined by E. Hückel as the sum of absolute values of the eigenvalues of the adjacency matrix during the search for a method to obtain approximate solutions of Schr¨odinger equation which include the ... -

One-dimensional cutting stock problem with divisible items: a case study in steel industry
(Işık University Press, 2019)This paper considers the one-dimensional cutting stock problem (1D-CSP) with divisible items, which arises in the steel industries. While planning the steel cutting operations, each item can be divided into smaller pieces, ... -
Geometric function optimization subject to mixed fuzzy relation inequality constraints
(Işık University Press, 2019)In this paper, the mixed fuzzy relation geometric programming problem is considered. The Mixed Fuzzy Relation Inequality (MFRI) system is an importance extension of FRI. It is shown that its feasible domain is non-convex ... -
Exponential domination of tree related graphs
(Işık University Press, 2019)The well-known concept of domination in graphs is a good tool for analyzing situations that can be modeled by networks. Although a vertex in the graph can exert influence on, or dominate, all vertices in its immediate ... -
